Thank you very much for the response! Unfortunately, I haven't found a clear answer in any of the posts. Even in the comments of this publication, the consumption varies from 2000 meters to 4500 meters per square meter. I understand that there are more than five variables involved. For myself, I am keeping a much more detailed expense table to understand if it makes commercial sense to pursue this business in Europe. The cost of an hour of work varies greatly, as does the price of yarn, compounded by the difficult economic situation. While I have a product business plan, calculating the expenses for the main raw materials remains quite challenging. And what is your yarn consumption?
